Regions: South Coast Inland.

A weaker storm passes us on Thursday night and a stronger storm on Friday night. Apply additional caution if you find substantial snow accumulation and slab properties.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

THURSDAY NIGHT: Cloudy with light snowfall, accumulation trace to 5 cm, freezing level rising to 1000 m.FRIDAY: Cloudy with light snowfall, accumulation trace to 5 cm, moderate southwest winds, alpine temperature -6 C, freezing level 1200 m.SATURDAY: Cloudy with snowfall, accumulation 10 to 20 cm, moderate to strong southwest winds, alpine temperature -4 C, freezing level 1300 m.SUNDAY: A mix of sun and clouds, light west winds, alpine temperature -7 C, freezing level 1000 m.

Avalanche Summary

No new avalanches were observed on Thursday.

Snowpack Summary

New snow will fall onto a sun crust on south aspects, a temperature crust on all aspects below around 1700 m, and feathery surface hoar in sheltered and shaded areas. The new snow may not bond well to these surfaces.Below this, the snowpack is generally well-settled.

Avalanche Problems

Wind Slabs

New snow is expected to fall with southwest winds. The highest amounts are expected in the south. This new snow may not bond well to underlying surfaces. Treat it with caution if enough snow accumulates, particularly if you notice slab properties.

Be careful with wind-loaded pockets, especially near ridge crests and roll-overs.Watch for signs of instability such as whumpfing, cracking, or recent avalanches.

Aspects: North, North East, East, South East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
